- In case of an Rx error instead of stopping the complete UART, only the Rx DMA is aborted and restarted.
- the UART communication is improved based on UART Idle line detection interrupt - an Rx ring buffer is used to manage the UART incoming data - both Tx and Rx are efficiently handled using DMA - fixed #1 Other: - minor visual improvements
- the sideboard can now send and receive Serial data from the mainboard - fixed Processing sketch
- minor bug fixes - added LED board picture
